I think you're referring to SYE kits, vs hack n' taps.
If it doesn't come with a new output shaft and housing, it's a hack n' tap, meaning you need to cut the tailshaft yourself.
Do whichever you'd like. They both work well. The advantages of the hack n' tap are price and simplicity. The advantage of the SYE kit is a stronger output shaft. Since you also have to open the TC to do it, you can check/replace the chain and add a TeraFlex 2low kit.
